Some people have CPUs that don't work with this game, namely Dual XEONs, if you are part of this group, I suggest you immediately issue a refund since the time you can issue one is limited.

These issues have existed in the past with other games and have up to date NOT been fixed (f.e. in Rainbow Six, Far Cry Primal, Steep etc.) , so it's unlikely they will ever going to be addressed properly by Ubisoft.

Do yourself and your wallet a favor and simply issue a refund. Let them know where it hurts them the most : in their wallet.

I'm done with this trash company and their 3rd rate devs that are unable to release a properly working game.
